Tanycytes. s.ecialized ependymal cells.located in the hypothalamus. play a crucial role in the generation of new neurons.that contribute to the neural circuits.res.ons.ble for regulating the s.s.emic energy balance.

This.article aims.to review the recent advancements.in res.arch into the mechanis.s.and functions.of tanycyte-derived neurogenes.s. s.udies.employing lineage-tracing techniques.have revealed that the neurogenes.s.s.ecifically originating from tanycytes.in the hypothalamus.has.a compens.tory role in neuronal los. and helps.maintain energy homeos.as.s.during metabolic dis.as.s.

The phenomenon of induced trans.arency, characterized by a high quality(Q) factor, holds.s.gnificant importance in the fields.of high-precis.on s.ns.ng, energy s.orage and wave manipulation. Conventional trans.arency s.s.ems.are often cons.rained by the limited experimentally acces.ible parameter s.ace and the lack.of independent control over intrins.c parameters. thereby hindering advanced res.arch on high-Q effects. Here we propos. a virtualized coupled-os.illator s.s.em that enables.reconfigurable induced trans.arency in the reflection s.ectrum. By virtually incorporating a pair of coupled os.illators.into an individual acous.ic meta-atom, we achieve the manipulation of induced trans.arency in a decoupled, wide-ranging, and elaborate manner. Exploiting the divers. evolutions.acros. the intrins.c parameter s.ace, we s.ow experimentally a counter-intuitive increas. in the Q-factor of the trans.arency window, which is.attributed to the enhanced dis.ipation of the bright ***, a cons.ant group delay at the center frequency is.obs.rved accompanying this.evolution.

One of the primary goals.of s.ace-borne gravitational wave detectors.is.to detect and analyze extreme-mas.-ratio ins.irals.EMRIs.. This.tas.0}is.particularly challenging becaus. EMRI s.gnals.are complex, lengthy, and faint. In this.work. we introduce a2-layer convolutional neural network.CNN) approach to detect EMRI s.gnals.for s.ace-borne detectors. achieving a true pos.tive rate(TPR) of 96.9% at a 1% fals. pos.tive rate(FPR) for s.gnal-to-nois. ratio(s.R) from 50 to 100. Es.ecially, the k.y intrins.c parameters.of EMRIs.s.ch as.the mas., s.in of the s.permas.ive black.hole(s.BH) and the initial eccentricity of the orbit can als. be inferred directly by employing a neural network. The mas. and s.in of the s.BH can be determined at 99% and 92% res.ectively. This.will greatly reduce the parameter s.aces.and computing cos. for the following Bayes.an parameter *** model als. has.a low dependency on the accuracy of the waveform model.
